So im trying to put a s5 motor in my s4 shell. Yeah i know its a lot of uneeded work but got the motor, tranny, and ecu for free so minus well put it in. Here is a couple questions if someone wouldnt mind answering.

1. I have the s5 under dash wiring going to the front lights and the engine harness. The problem is they are n/a how do i make it a TII harness?

2. Will the wiring harness for under the dash even plug in right?

3. Do i need a TII fuel pump?

4. And is there anything else im missing i know i need a new accelerator cable and TII diff and drivetrain?
